Our life is made up of Pancha Maha Bhutas. The Pancha Maha Bhutas are self-existent. The coming together of those elements gave birth to a new invention in the creation of life. Over time, this creation decays and they merge back into the Panchatatva. So be it animate or inanimate, this rule applies equally to both.
The creation of the entire universe is based on five basic elements, the earth element, the air element, the water element, the fire element and the celestial element. Through these five elements, our body gets the internal tonic elements, proteins, carbohydrates and fats. So heat, light, sound and air provide external energy.
